[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example: Figure 1-6As shown, this utility model provides a power supply box ventilation and heat dissipation structure, including a box body 1, a mounting plate 11, a reserved space 12, a first ventilation and heat dissipation port 13, and a second ventilation and heat dissipation port 14. The mounting plate 11 is fixedly installed inside the box body 1, and the reserved space 12 is located between the mounting plate 11 and the side wall of the box body 1. The first ventilation and heat dissipation port 13 is located on the mounting plate 11, and the second ventilation and heat dissipation port 14 is located on the upper end face of the box body 1. When electronic components are installed on the mounting plate 11 and generate heat, the heat enters the reserved space 12 through the first ventilation and heat dissipation port 13 and is then discharged outward through the second ventilation and heat dissipation port 14. This is the prior art disclosed in the comparative case and will not be described in detail here. A heat dissipation component 2 is provided on one side of the box body 1. By setting the heat dissipation component 2, the heat dissipation speed inside the box body 1 can be improved, thereby improving the heat dissipation performance of the box body 1, and thus improving the operating efficiency and service life of the electronic components. An installation component 4 is provided on the lower end face of the box body 1. By setting the installation component 4, it is convenient to adjust the horizontal position of the box body 1 after installation.

[0027] The heat dissipation assembly 2 includes a cover 21, which is detachably installed on one side of the housing 1. An equipment box 22 is detachably installed on one side of the cover 21. A fan 23 is fixedly installed inside the equipment box 22. A fixing plate 24 is fixedly installed on one side of the equipment box 22. The fixing plate 24 is provided with several holes 25, 251 and 252. The holes 25 and 252 are inclined. By setting the fan 23, fixing plate 24, holes 25, 251 and 252, when the fan 23 is working, the airflow generated can enter the housing 1 through the holes 25, 251 and 252, thereby increasing the heat dissipation speed. By setting the inclined holes 25 and 252, the airflow entering the housing 1 can be guided, so that the airflow can fully contact the various electronic components on the mounting plate 11.

[0028] Both sides of the cover 21 are threadedly fitted with several No. 1 bolts 26. Both sides of the housing 1 are fixedly fitted with several mounting seats 27. One end of the No. 1 bolt 26 is threadedly connected to the threaded hole on one side of the mounting seat 27. By setting the No. 1 bolt 26, the cover 21 can be installed on one side of the housing 1. At the same time, the cover 21 can be disassembled to separate the cover 21 from the housing 1 for easy maintenance and repair. A No. 1 sealing ring 28 is fixedly installed on the side of the cover 21 away from the equipment box 22. A U-shaped groove 29 is provided on one side of the housing 1. The No. 1 sealing ring 28 and the inner wall of the U-shaped groove 29 are in contact. By setting the No. 1 sealing ring 28 and the U-shaped groove 29, when the cover 21 is installed on one side of the housing 1, the No. 1 sealing ring 28 is inserted into the U-shaped groove 29, which can improve the sealing between the cover 21 and the housing 1.

[0029] Both sides of the equipment box 22 are threadedly mounted with several No. 2 bolts 3. One end of the No. 2 bolts 3 is threadedly connected to the threaded hole on one side of the box cover 21. By setting the No. 2 bolts 3, the equipment box 22 can be installed on one side of the box cover 21, and the equipment box 22 can also be disassembled for easy maintenance and repair.

[0030] A second sealing ring 31 is fixedly installed on one side of the equipment box 22, and a groove 32 is provided on the box cover 21. The outer wall of the second sealing ring 31 and the peripheral wall of the groove 32 are in contact. By setting the second sealing ring 31, the sealing performance between the equipment box 22 and the box cover 21 can be improved.

[0031] Mounting assembly 4 includes a mounting base plate 41, which is movably mounted on the lower end face of the housing 1. Both ends of the mounting base plate 41 have several mounting holes 42. By using the mounting base plate 41 and mounting holes 42, and with the help of bolts, the mounting base plate 41 can be mounted on an external platform. Ear plates 43 are fixedly mounted on both sides of the housing 1. The lower surface of the ear plates 43 is in contact with the upper surface of the mounting base plate 41. The ear plates 43 have grooves 44, and several locking bolts 45 are movably mounted within the grooves 44. The nuts of the locking bolts 45 are in contact with the upper surface of the ear plates 43. The mounting base plate 41 has several threaded sleeves 46. One end of each locking bolt 45 is threadedly connected to the inner wall of a threaded sleeve 46. By using the ear plates 43, grooves 44, locking bolts 45, and multiple equidistantly distributed threaded sleeves 46, the horizontal position of the housing 1 can be adjusted.

[0032] Working principle: When the horizontal position of the housing 1 needs to be adjusted, the operator rotates multiple locking bolts 45 counterclockwise to disengage them from the corresponding threaded sleeves 46. Then, the housing 1 is moved horizontally on the mounting base plate 41. Once the desired position is reached, the movement of the housing 1 is stopped. The multiple locking bolts 45 are then vertically inserted into the corresponding grooves 44 and screwed into the corresponding threaded sleeves 46. At the same time, the nuts of the multiple locking bolts 45 are tightened. This allows the installation position of the housing 1 to be adjusted, improving flexibility.

[0033] During the operation of the electronic components inside the enclosure 1, as the electronic components generate heat, the operator starts the fan 23. The airflow generated by the fan 23 enters the enclosure 1 through multiple holes 25, 251, and 252. After being guided by the holes 25, 251, and 252, the airflow fully contacts the various electronic components on the mounting plate 11, cooling the electronic components on the mounting plate 11. At the same time, the heat inside the enclosure 1 is vented into the reserved space 12 through the first ventilation vent 13, and then quickly discharged outward through the second ventilation vent 14, increasing the heat dissipation speed inside the enclosure 1, thereby improving the heat dissipation performance of the enclosure 1, and thus improving the operating efficiency and service life of the electronic components.

[0034] All standard parts used in this invention can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0035] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
